The reason I bought this:
I already have a mostly full harness. That will be my main one. I would like to have a "field harness", something that I can put on without another person there, so that I can wear it to demos and such. So basically I'm looking at this breast plate, my current legs, a helmet and gauntlets. I could use my current cuirass, but its tricky to put on by myself.
But if I'm going to put together a second harness, it dawned on me that I could make a completely different kit with it. So what I'm planning on doing is blueing this, but using gilt paint to line the edges. (This is inspired by projects that Sean Flynt was working on.) I will also get another helmet at some point... I was thinking of getting a GDFB sallet and taking off the visor. This would also be blued with gilt paint. Eventually I'll upgrade my leg harness for my main harness with something nicer, so the GDFB ones I already have will eventually get the blued/gilt treatment as well.
So I'll have my main "nice" harness, which will continue to get upgraded over time with nicer pieces, and a back up one made with inexpensive but decent pieces that can also work for passing around at demos if I'm not wearing them.
